Updated
- Adagrad
- Adamax
- Adam
- AdamW
- RAdam
make multi_tensor functionals take `state_steps: List[Tensor]` instead of taking `states: List[Dict]`
make `state_steps: List[int]s -> state_steps:List[Tensor]` where each is a Singleton tensor so step can be updated within the functional
(NAdam and ASGD) were updated in separate diffs to fold their handling of state into the functionals

(cherry picked from commit 831c02b3d0)
Summary:
Solves the next most important use case in https://github.com/pytorch/pytorch/issues/68052.
I have kept the style as close to that in SGD as seemed reasonable, given the slight differences in their internal implementations.
All feedback welcome!

Pull Request resolved: https://github.com/pytorch/pytorch/pull/62611
Enables optimizer overlap with backwards in DDP for Adam. Additional optimizers, especially Adagrad will be done in follow up diffs.
1. Implement `step_param` method based on `step` in _FunctionalAdam (perf permitting we can later dedupe `step` to call `step_param`
2. Modify tests to test all current functional optimizers.
